I've been using my Yaesu FT-2900R as a base station with a N9TAX Slim Jim. I currently have it on a painters pole which is about 16" total. I have the painters pole stuck in a huge traffic cone which keeps it uprright.

Anyway, I'm looking to throw something up on the roof. I'm wondering if I should just mount the Slim Jim up there on a bow made of PVC or if I should get something else. The Slim Jim is omnidirectional. For working repeaters is it better to get a directional? I was looking at the Elk 5-element one for example. Would I be able to hit repeaters on Cheyenne Mtn and Pikes Peak without moving the directional or would I have to put it on some kind of antenna rotator?
